Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1, fig. 1 is a schematic diagram of a network structure to which the embodiment of the present invention is applicable, and as shown in fig. 1, the network structure includes a terminal 11 and a network side device 12, where the terminal 11 may be a User Equipment (UE) or other terminal devices, for example: it should be noted that, in the embodiment of the present invention, a specific type of the terminal 11 is not limited, and the terminal may be a terminal-side Device such as a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), or a Wearable Device (Wearable Device). The network side device 12 may be a base station, for example: macro station, LTE eNB, 5G NR NB, etc.; the network side device 12 may also be a small station, such as a Low Power Node (LPN), pico, femto, or the network side device 12 may be an Access Point (AP); the base station may also be a network node that is composed of a Central Unit (CU) and a plurality of Transmission Reception Points (TRPs) whose management is and controls. It should be noted that the specific type of the network-side device 12 is not limited in the embodiment of the present invention.

Referring to fig. 2, fig. 2 is a flowchart of a resource allocation method according to an embodiment of the present invention, as shown in fig. 2, including the following steps:

201. a terminal receives DCI sent by network side equipment in an activated BWP (activated BWP), wherein the DCI comprises an RA domain;

202. and the terminal determines the resource allocation information indicated by the RA domain according to the size of the active BWP.

The active BWP may be an active BWP for the terminal, and the active BWP may also be referred to as a current BWP of the terminal.

The DCI may be a DCI for scheduling the terminal to perform data transmission, and the RA field may be used to instruct a network-side device to allocate resources for data transmission, so that the data transmission performed by the terminal in the active BWP occupies the resources indicated by the RA field.

The size of the active BWP may also be referred to as the actual size of the active BWP, for example: the number of RBs included in the active BWP, or the number of resource allocation granularities for resource allocation within the active BWP, where the resource allocation granularity for resource allocation here may be the resource allocation granularity for which resources are available for allocation.

The terminal may determine the resource allocation information indicated by the RA field according to the size of the active BWP, where the terminal analyzes the RA field according to the size of the active BWP to determine the resource allocation information indicated by the information bits of the RA field, and the resource allocation information may include: the resource allocation information indicates that the data transmission occupies 0 th to 10 th VRBs, or the resource allocation information indicates that the data transmission occupies 0 th to 20 th VRBs, and so on.

Since the length of the RA field within the DCI may be determined by the initial DL BWP, the size of the active BWP may be different from the size of the initial DL BWP, for example: the active BWP of the terminal may be much larger than the initial DL BWP or smaller than the initial DL BWP, so that the resource allocation information indicated by the RA field is determined according to the size of the active BWP, thereby improving the flexibility of resource allocation, avoiding changing the length of the RA field, and reducing the complexity of resource allocation.

The activation BWP may include all of the CORESET0, and the CORESET0 may be located completely within the activation BWP. In this embodiment, since the active BWP includes all of the CORESET0, the user terminal only needs to search within the CSS of the CORESET0 to reduce the power consumption of the user terminal.

Optionally, the DCI includes a DCI in which a CRC code is scrambled using a specific RNTI; and/or

The length of the RA field is determined for one VRB according to resource allocation granularity according to the size of an initial (initial) BWP of the terminal.

Wherein the specific RNTI includes, but is not limited to, a Cell Radio Network Temporary Identifier (C-RNTI) or a Temporary Cell Radio Network Temporary Identifier (TC-RNTI) or a configuration Scheduling Radio Network Temporary Identifier (CS-RNTI) or a Semi-Persistent Channel State Information Radio Network Temporary Identifier (Semi-Persistent Channel State Information Radio Network Temporary Identifier, SP-CSI-RNTI), or an RNTI related to unicast (unicast) Scheduling, such as CSs transmission fallback (unicast) DCI in core eset es 0.

The initial BWP may be an initial downlink BWP (initial DL BWP). In this embodiment, although the length of the RA field is determined for one VRB according to the resource allocation granularity based on the size of the initial (initial) BWP of the terminal, the terminal determines the resource allocation information indicated by the RA field based on the size of the active BWP when parsing the RA field, thereby improving the flexibility of resource allocation.

As an optional implementation manner, the determining, by the terminal, the resource allocation information indicated by the RA field according to the size of the active BWP includes:

and the terminal determines the resource allocation granularity of the RA domain according to the size of the activated BWP and determines the resource allocation information indicated by the RA domain according to the resource allocation granularity.

The resource allocation granularity of the RA field may be, for example, the resource allocation granularity used for analyzing the RA field: one VRB, or two VRBs, etc. The determining of the resource allocation information indicated by the RA field according to the resource allocation granularity may be analyzing the RA field according to the resource allocation granularity to determine the resource allocation information.

It should be noted that, when the resource allocation granularity of the RA field is determined, the resource allocation information indicated by the RA field is determined. For example: if the resource allocation granularity is 2 VRBs and the information bits in the RA field indicate the 0 th to 5 th resource units, each resource unit is determined to be 2 VRBs, that is, the resource allocation information indicated by the RA field is the 0 th to 10 th VRBs; another example is: the resource allocation granularity is 2 VRBs and the RA field includes a bitmap, each bit in which represents 2 VRBs.

In addition, the terminal may determine the resource allocation granularity of the RA field according to the size of the active BWP, where the terminal determines the resource allocation granularity according to the size of the active BWP and the length of the RA field, for example: the terminal may determine the resource allocation granularity according to a mapping relationship between a pre-configured BWP size, an RA field length, and the resource allocation granularity. Or, the terminal may determine the resource allocation granularity of the RA domain according to the size of the active BWP, where the terminal determines the resource allocation granularity according to a mapping relationship between the size of the active BWP and the resource allocation granularity, which is obtained in advance.

In this embodiment, since the resource allocation granularity of the RA field is determined according to the size of the active BWP, the flexibility of resource allocation is further improved, and the length of the RA field does not need to be adjusted according to the size of the active BWP, so as to save implementation cost.

and the terminal determines the resource allocation granularity of the RA domain according to the comparison result of the size of the active BWP and the size of the initial BWP.

Since the length of the RA field in the DCI may be determined by the initial BWP, in this embodiment, determining the resource allocation granularity according to the comparison result may implement that, under the condition that the length of the RA field is not changed, different resource allocation information may be indicated according to different activated BWPs, so as to further improve the flexibility of resource allocation, and further avoid changing the length of the RA field, thereby reducing the complexity of resource allocation. .

when the size of the active BWP is larger than the size of the initial BWP, the terminal determines that the resource allocation granularity of the RA domain is N VRBs, where N is an integer rounded down to a quotient, and the quotient is the quotient of the size of the active BWP divided by the size of the initial BWP; or

The active BWP may have a size equal to the number of RBs included in the active BWP, the initial BWP may have a size equal to the number of RBs included in the initial BWP, and the N may be a G-floor (BWP) _current /BWP _initial ) Determination, wherein G has the value N, floor denotes rounded-down, BWP _current Indicates the number of RBs contained in active BWP, BWP _initial Indicates the number of RBs included in the initial BWP. Of course, in the embodiment of the present invention, the size of the BWP is not limited to the number of RBs included in the BWP, and for example: the number in units of other resource granularities may also be used.

For example: as shown in fig. 3, CORESET0 configured by PBCH is located entirely within active BWP, and the network side device sends DCI scheduling unicast (unicast) data transmission within CSS in CORESET0, where the CRC of DCI is scrambled by C-RNTI, although other types of RNTIs such as TC-RNTI, CS-RNTI, or SP-CSI-RNTI are not excluded.

Assuming that active BWP is larger than initial BW, resource allocation granularity is defined by the formula G-floor (BWP) _current /BWP _initial ) Determination, where floor denotes round-Down, BWP _current Indicates the number of RBs contained in the active BWP, BWP _initial Indicates the number of RBs included in the initial BWP. Book (I)In the example, assuming that the initial DL BWP includes 25 Physical Resource Blocks (PRBs), and the active BWP includes 50 PRBs, G-floor (50/25) -2. After detecting the RA field in the received DCI, the terminal understands that the RA field is 2 VRBs according to the resource allocation granularity. For example, the RA field (also referred to as a resource indication field) indicates that data transmission of the terminal in the active bwp (activated bwp) occupies resource units 0 to 5, and accordingly, the occupied resource positions are VRBs 0 to 10. When the active BWP is smaller than the initial BWP, the resource allocation granularity is 1 VRB.

Similarly, M may also be defined by the formula G ═ ceil (BWP) _current /BWP _initial ) Determining that G has the value M, ceil indicates rounding-up, BWP _current Indicates the number of RBs contained in active BWP, BWP _initial Indicates the number of RBs included in the initial BWP.

For example: CORESET0 configured by PBCH is located entirely within active BWP, and the network side device sends DCI scheduling unicast (unicast) data transmission within CSS in CORESET0, where the CRC of DCI is scrambled by C-RNTI in this example, although other types of RNTIs such as TC-RNTI, CS-RNTI, or SP-CSI-RNTI are not excluded.

Assuming that active BWP is larger than initial BW, resource allocation granularity is defined by the formula G-ceil (BWP) _current /BWP _initial ) Determine, where ceil denotes rounded-up, BWP _current Indicates the number of RBs contained in active BWP, BWP _initial Indicates the number of RBs included in the initial BWP. In this example, assuming that the initial BWP includes 25 PRBs and the active BWP includes 50 PRBs, the terminal detects the RA field in the received DCI and then understands the RA field as 2 VRBs according to the resource allocation granularity. For example, the RA field (also referred to as resource indication field) indicates that the terminal occupies resource units 0 to 5 in the activated BWP, and the occupied resource locations are VRBs 0 to 10 accordingly. When the activated BWP is smaller than the initial DL BWP, the resource allocation granularity is 1 VRB.

In this embodiment, since the resource allocation granularity of the RA field may be determined to be N or M VRBs when the size of the active BWP is larger than the size of the initial BWP, or may be directly determined to be 1 VRB when the size of the active BWP is smaller than or equal to the size of the initial BWP, the flexibility of resource allocation may be directly and further improved.

The number of resource allocation granularities for resource allocation in the active BWP may be the number of resource allocation granularities (M VRBs) available for resource allocation in the active BWP.

and the terminal performs filling operation (padding operation) or intercepting operation (truncate operation) on the RA domain according to the size of the activated BWP to obtain target information, and determines resource allocation information according to the target information.

The determining of the resource allocation information according to the target information may be determining the resource allocation information indicated by the target information. In addition, in this embodiment, the resource allocation information indicated by the target information may be determined for 1 VRB according to the resource allocation granularity.

In this embodiment, since the padding operation or the interception operation may be performed on the RA field according to the size of the active BWP, and the resource allocation information may be determined according to the obtained information, the flexibility of resource allocation may be further improved.

In addition, in this embodiment, the padding operation or the clipping operation may be determined to be performed according to a mapping relationship between the size of the BWP acquired in advance and the operation, and the length of the padding operation or the clipping operation may be further determined. Preferably, the above terminal performs a padding operation or an interception operation on the RA domain according to the size of the active BWP to obtain target information, and determines resource allocation information according to the target information, including:

Since the length of the RA field in the DCI may be determined by the initial BWP, in this embodiment, the RA field is determined to be filled or intercepted according to the comparison result, and then the resource allocation information is determined, so that under the condition that the length of the RA field is not changed, different resource allocation information may be indicated according to different activated BWPs, thereby further improving the flexibility of resource allocation, and also avoiding changing the length of the RA field, and reducing the complexity of resource allocation. .

In this embodiment, the RA field may be filled when the size of the active BWP is larger than the size of the initial BWP, and the RA field may be intercepted when the size of the active BWP is smaller than the size of the initial BWP, so that resource allocation may be performed on active BWPs with different sizes when the RA length in DCI sent by the network side device is not changed, so as to improve flexibility of resource allocation, and further avoid changing the length of the RA field, and reduce complexity of resource allocation.
